Coinbase Bitcoin Premium Index Negative for 90 Days in a Row

The Coinbase Bitcoin Premium Index has been negative for ninety consecutive days, from 19 May through 16 August. This is according to data from CoinGlass and is the longest negative streak ever recorded. The index currently stands at -0.1066%. Bitcoin is trading at around $63.005 at the moment.

Bitcoin is available at OKX and Bybit.

In brief:

• The Coinbase Bitcoin Premium Index has been negative for 90 consecutive days, a new record.
• The index measures the price difference of Bitcoin between Coinbase Pro and Binance.
• A persistently negative value can point to weaker buying pressure from the US, but does not in itself prove structural institutional outflows.

What the index measures and what it says

The Coinbase Bitcoin Premium Index compares the Bitcoin price on Coinbase Pro with that on Binance. When the index is positive, buyers on Coinbase pay more than on Binance, which usually points to relatively strong demand from the United States. A negative value means the opposite: Bitcoin is cheaper on Coinbase than on Binance.

According to WuBlockchain, a persistently negative reading can point to weaker US buying pressure or, alternatively, to greater selling pressure on the part of Coinbase users. However, this does not automatically mean that institutional parties are structurally exiting.

Negative trend coincides with pressure on the price

The ninety-day negative streak began on 19 May, a period in which support under Bitcoin also came under pressure. During that same period, the market saw several moments of outflows from Bitcoin ETFs, which reinforces the broader picture of declining demand from the US.

Whether the negative premium on Coinbase is a direct precursor of further price pressure remains unclear. The index is one signal and says nothing about the short-term direction of the market. Investors and analysts typically use the gauge as additional context alongside other indicators of supply and demand.
